Abstract

PURPOSE: To simplify the structure of a magnetic shielding material, by providing an amorphous metallic magnetic material on the back of a tape running part.
CONSTITUTION: An amorphous metallic magnetic material is provided on the back of a part where a magnetic tape 17 runs. For example, a magnetic shielding material 22 consisting of an amorphous alloy is inserted between holding members 23a and 23b and is provided on the back of an elastic plate 20 consisting of a phosphorus bronze plate to which a pad 21 for pressing the tape 17 to a sound recording and reproducing head is stuck. An amorphous alloy ribbon (thickness 50μm) having composite (CO0.88Fe0.06Ni0.04Nb0.02)75Si10B15 obtained by the liquid quenching method is punched to a square, and this obtained material is used as the magnetic shielding plate 22.
